Despite the alert issued to the local population on the same day advising people not to consume the contaminated water, cases of acute gastroenteric diseases were subsequently observed. Considerable faecal contamination was detected the day after the incident in water samples taken up to 500 m from the sewage plant. In a retrospective epidemiological study involving 240 persons living in the affected area, 126 cases of acute gastrointestinal illness were documented. The epidemic curve revealed a peak incidence two days after the event. Stool samples from 11 of 20 patients were positive for noroviruses or Campylobacter jejuni. Although these microorganisms were not detected in the contaminated water, the subsequently conducted case\u2013control study among the surveyed population showed that consumption of contaminated drinking water was associated with gastrointestinal illness (odds ratio 29.1; 95% confidence interval: 9.8\u201386.4; p = 0.001). The study also revealed the very probable time period of infection. We present the dimension and chronology of this outbreak and discuss the reasons for its localised and temporary spread.<\/jats:p>","DOI":"10.2166\/wh.2011.158","type":"journal-article","created":{"date-parts":[[2011,8,2]],"date-time":"2011-08-02T10:02:03Z","timestamp":1312279323000},"page":"569-576","update-policy":"https:\/\/doi.org\/10.2166\/iwapcrossmarkpolicypage","source":"Crossref","is-referenced-by-count":25,"title":["Outbreak of acute gastroenteritis due to a washwater-contaminated water supply, Switzerland, 2008"],"prefix":"10.2166","volume":"9","author":[{"given":"A.","family":"Breitenmoser","sequence":"first","affiliation":[{"name":"Official Food Control Authority of Zurich, CH-8032 Zurich, Switzerland"},{"name":"Current address: Office for Consumer Protection, Canton Aargau, Obere Vorstadt 14, CH-5000 Aarau, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.","family":"Fretz","sequence":"first","affiliation":[{"name":"Federal Office of Public Health, CH-3003 Bern, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Schmid","sequence":"first","affiliation":[{"name":"Official Authority of Health and Consumer Protection of St Gallen, CH-9001 St Gallen, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Besl","sequence":"first","affiliation":[{"name":"Official Food Control Authority of Zurich, CH-8032 Zurich, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.","family":"Etter","sequence":"first","affiliation":[{"name":"Official Food Control Authority of Zurich, CH-8032 Zurich, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"945","published-online":{"date-parts":[[2011,4,29]]},"container-title":["Journal of Water and Health"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/iwaponline.com\/jwh\/article-pdf\/9\/3\/569\/395976\/569.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"http:\/\/iwaponline.com\/jwh\/article-pdf\/9\/3\/569\/395976\/569.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,3,26]],"date-time":"2020-03-26T22:50:50Z","timestamp":1585263050000},"score":1,"resource":{"primary":{"URL":"https:\/\/iwaponline.com\/jwh\/article\/9\/3\/569\/19821\/Outbreak-of-acute-gastroenteritis-due-to-a"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011,4,29]]},"references-count":0,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2011,4,29]]},"published-print":{"date-parts":[[2011,9,1]]}},"URL":"https:\/\/doi.org\/10.2166\/wh.2011.158","relation":{},"ISSN":["1477-8920","1996-7829"],"issn-type":[{"value":"1477-8920","type":"print"},{"value":"1996-7829","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[2011,9,1]]},"published":{"date-parts":[[2011,4,29]]}}}
